There is still a memory leak in the latest beta.
The il2launcher process eventually gets to the maximum allowed memory - 2 gig - at that stage the server just throws never ending exceptions, taking up 100% of the cpu core assigned to the process.
For dedicated server operators it's not going to matter if you have 4 or 400 gig of memory in your box, when you hit the 2 gig limit you're stuffed.
